Marine Iguanas are the only marine lizard species in the world found only in the Galápagos Islands. They can dive as deep as 30m (98 feet) and hold their breath for 30-40 minutes.
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Manatees (/ ˈ m æ n ə t iː z /, family Trichechidae, genus Trichechus) are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows.There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee (Trichechus inunguis), the West Indian manatee (Trichechus manatus), and the West ...
Reef life and oceanic processes create opportunities for the exchange of seawater, sediments, nutrients and marine life. Most coral reefs exist in waters less than 50 m deep. [56] Some inhabit tropical continental shelves where cool, nutrient-rich upwelling does not occur, such as the Great Barrier Reef.
This is great news for sea otter conservation. Many aquariums pair orphaned sea otter pups with surrogate moms in an attempt to teach the pups what they need to know to be released back into the wild.
The most proliferative extant group are the marine mammals, such as Cetacea (whales, dolphins and porpoises, with some freshwater species) and Sirenia (dugongs and manatees), who are too evolved for aquatic life to survive on land at all (where they will die of beaching), as well as the highly aquatically adapted but land-dwelling pinnipeds ...
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy .
Sea grass is the only type of flowering plant that grows in British seas, but it nonetheless forms vast beds. Invertebrates in coastal Britain are very diverse and include brittle stars, hermit crabs, mussels, prawns, sponges, sea anemones and sea squirts. Efforts are made to conserve rare plants and animals in nature reserves.
